I. INTRODUCTION

1.1) About Japan Society of Civil Engineers ( JSCE) Japan Society of Civil Engineers (JSCE) was established as an incorporated association in 1914 entrusted with the mission to contribute to the advancement of scientific culture by promoting the field of civil engineering and the expansion of civil engineering activities. Since its establishment, JSCE has endeavored to achieve the above mission, through extensive activities including scientific exchange among members, researchers / promotion of science and technologies relating to the field of civil engineering, social involvement, etc. Over the years, the JSCE membership has increased significantly from the initial 443 members to approximately 39,000 members at present, and is currently engaged in various wide-ranged activities around the world. With the birth of the 21st century, JSCE has reconfirmed its goals to exert perpetual efforts 1) to propose an idea for social infrastructure development in the future from civil engineers' perspective, 2) to acquire a steadfast relationship of mutual trust with the society, 3) to promote scientific and technological researches/studies with a high degree of transparency, and 4) to evaluate public works from a neutral standpoint, and to reach a social consensus on those proper standards.

1.2) About Study Tour Grant ( STG) JSCE Study Tour Grant (STG) is supported by International Scientific Exchange Fund (ISEF).

We left for Haneda Internation Aiport later that day to catch the flight ANA 075 to New Chitose Airport in Hokkaido. We took the bus to Sumire Hotel, Sapporo. The weather was much more cooler than Tokyo, but we were all on fire. Yes, we would have our presentations at the International Summer Symposium tomorrow.

2.5) Day 4-August 29th 2018 We left early in the morning to Hokkaido University to attend the 20th International Summer Symposium, organised by JSCE. We participants were divided into different venues to deliver our presentation. I was in the same auditorium as Mr. Ali and Ms. Phyu Phyu. I was the 7th presenter in the list. My presentation was “ Research on developing a suitable superstructure for short span low cost concrete bridges in the Northern Mountainous Regions of Vietnam”, in which I introduced our suggested model of bridge and I explained why we believe our model is the most

After having lunch at the university, we followed the schedule of the program to the following places:  Ishikari River Museum  Oyafuru Cut-off Channel  Makunbetsu Marsh  Canal Sluice  Ishikari River Drain  Ishikari River Estuary We were given an amazing tour about the history and development of the flood control system of the Ishikari river, first developed by Dr.Okazaki’s investigation in 1899. From then until now, the Ishikari river’s flood control system has changed the surrounding area of the river significantly, not only be able to preserve natural habitat but also boosts agricultures in the region. We were surprised to see the main monitoring system was placed in the river museum itself.

2.6) Day 5-August 30th 2018 In the morning, we visited the Ishikariwan Shinko Thermal Power Station. The Power Station consists of two side:  Power Station side: Ishikariwan Shinko Power Station Unit 1 and the Construction Work.  Base side: Ishikari LNG Tank and Base Expansion Work The Power Station is fueled by natural gas with a combined cycle type Power Generation System. Gas is supped from Ishikari LNG Base, operated by Hokkaido Gas Co., Ltd through gas piping. 3 units are to be constructed, which the first one is duel to be commercially used by February 2019 and the last one is to be used by December 2030.

Figure 15. Participants in front of the LNG Tank After the visit, we took a two-hour ride on the coastal of Hokkaido to the Toya-Unesco Global Geopark. We arrived at the Toya Volcano Science Museum and was enthusiastically introduced by “ Mr.Volcano Meister”, who is a volcano expert and works at the Museum. He took us around the museum, as well as the surrounding area and show us all the damages caused to the infrastructures in the region due to volcanic activitities. We were all surprised when he told us that althought being frequently disrupted by Mount Usu volcano, the number of fatal accident caused by the volcano in Toya region is actually zero!
